Restore smooth, effort-saving hydraulic steering assist with the CARDONE Remanufactured Power Steering Pump 21-5028 (also written 215028). It drops in as a direct-fit replacement for the 1997-2000 Infiniti QX4 and 1996-2000 Nissan Pathfinder — see the Buyer's Guide tab to confirm the engine for your vehicle. The pump pressurizes power steering fluid to deliver the hydraulic assist your steering system needs, and this remanufactured unit is engineered to meet or exceed O.E. performance, with design upgrades applied where the original could be improved.
- Triple-tested internals: critical components such as campacs and spool valves are triple-tested for reliability.
- 100% new sealing: built with all-new O-rings and premium-grade HNBR seals to help prevent leaks; HNBR resists breakdown at high temperatures unlike conventional seal material.
- Surfaced shafts: shafts are surfaced to precise specifications to reduce premature seal wear and extend pump life.
- Calibrated & computer-tested: supplied with 100% tested, calibrated pressure relief valves, and the final assembly is computer-tested for pressure, bypass, fluid flow, valve operation, steering effort and noise.
The earth-friendly remanufacturing process reduces the energy and raw material of a new part by about 80%. If a worn or leaking pump is the source of your heavy or noisy steering, this unit replaces it.
